Golang恐慌：运行时错误：索引超出范围

Question

Hi This function takes an array with some integers and my goal is to have a new array with just positive integers. However, I am keep getting the same error saying panic: runtime error: index out of range

Can anybody please help me..??

func domath(newarray[] int, i int, array[] int)([]int){
    if i < len(newarray) {
        if newarray[i] < 0{
            i ++    
            domath(newarray, i, array)
        }
        if newarray[i] >= 0 {
            array = append(array, newarray[i])
            i ++
            domath(newarray, i, array)
        }
    }
    return array 
}

Answer 1

Do you want write a recursive function?, you can see my code below :

func domath(newarray []int, i int, array []int) []int {
if i < len(array) {
    if array[i] >= 0 {
        newarray = append(newarray, array[i])
    }
    i++
} else {
    return newarray
}
return domath(newarray, i, array)

}
